The display module 18 may comprise several components, including a display 22, an optic block 24, a heat sink 26, and a primary printed circuit board (PCB) 28. The PCB 28 operates to provide electrical power and control for the components of the camera unit 20, the display module 18, and the glass element 12. The front shield 14, the rear shield 16, and components of the display module 18 include various retaining features to operably connect the several components of the display module 18 with the front shield 14, the rear shield 16, and each other, and to provide support to the display module 18. Specifically, the front shield 14 includes retaining features to operably connect the front shield 14 to the display module 18, and the rear shield 16 has retaining features to operably connect the rear shield 16 to the display module 18.

The present disclosure may be used with a mounting system, such as that described in U.S. Pat. Nos. 9,244,249; 8,960,629; 8,814,373; 8,201,800; 8,210,695; 9,174,577; 8,925,891; and 9,838,653; and U.S. Provisional Patent Application No. 61/704,869, which are hereby incorporated herein by reference in their entirety. Further, the present disclosure may be used with a rearview packaging assembly, such as that described in U.S. Pat. Nos. 9,316,347; 8,814,373; 8,646,924; 8,643,931; 8,264,761; and 8,885,240; and U.S. Provisional Patent Application No. 61/707,625, which are hereby incorporated herein by reference in their entirety. Additionally, it is contemplated that the present disclosure can include a bezel, such as that described in U.S. Pat. Nos. 8,827,517; 8,210,695; and 8,201,800, which are hereby incorporated herein by reference in their entirety.
Accordingly, in some embodiments, the ECU 202 may be located in the housing 30 and the camera unit 20 may be located outside of the housing 30, where the ECU 202 is configured to operate various functionalities of the camera unit 20. For example, the processor 204 may be configured to turn the camera unit 20 on and off, instruct the camera unit 20 to capture the image data 212 in ambient lighting conditions, turn on and off the illumination elements 70, capture the image data 212 in infrared illumination, etc. In some embodiments, the ECU 202 may further be configured to also operate various functionalities of the glass element 12 (e.g., sourcing power to the electro-optic medium 37), the display module 18 (e.g., displaying image information), and the optic block 24 (e.g., removing glare as sensed from the glare sensor optic 84). Therefore, in some embodiments, the ECU 202 may be configured to receive, upon a request to camera unit 20, image data 212, and compare the image data 212 to defined parameters in the parameter data 210, and to extrapolate and relay (e.g., via the software 208) at least one image information. For example, the captured image data 212 may include that a driver and/or a passenger is using a mobile electronic device, is exhibiting signs of drowsiness, distraction, medical symptoms, and/or is sitting in an unsafe position within the interior cabin. The image data 212 may also include certain types of redundant information that is typically observed through other components of a vehicle, such as a passenger or driver that is not wearing a seatbelt. The image data 212 may then be reviewed via instructions in the parameter data 210 to identify any notable unsafe conditions and relay that information as an auditory or graphical message on the display module 18. The information related may, therefore, be a recommendation that is displayed on the display module 18 as a textual or a non-textual indicia. In some embodiments, an auditory alert may accompany the graphical message that is displayed on the display module.
It should be appreciated that the flexible design of the mirror assembly 10 with a single ECU 202 reduces the number of ECUs typically needed for camera units 20 located outside of a housing 30. Moreover, the single ECU design reduces the number of required wire harness connections and allows the mirror assembly 10 to be shipped with the camera unit 20 temporarily attached, reducing on-site errors during attachment to a vehicle.
